BARBED FENCE.

SPECIFICATION forming part of Letters Patent No. 255,399, dated March 21, 1882.

Application filed September is, 1881. N6 model.)

. To all whom it may concern:

Be it known that I, ANDREW J. UPHAM, a citizen of the United States, residing at Sterling, in the county of Whiteside and State of Illinois, haveinveuted certain new and useful Improvements in Barbed Fences; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a partofthis specification.

My invention consists in a simple, rapid, and cheap mode of making barbed-fence material by fixinga wire or metallic barb upon a tlat metallic strip.

In the drawings, Figure l rcpresen ts the metallic strip prepared to receive the barb. Fig. 2 is a section ofsuch strip, showing the conformation of the receptacle for the barb. Fig. 3 is a section of the metal strip provided with the barbs.

A is a strip or ribbon, ofsteel, iron, or other metal suitable for fence material, and may be of any desired width and thickness. I find, however, that a width of scvensixteenths of an inch is preferable.

B is the barb, of any desired length, and having its ends cut diagonally to furnish sharp points.

In the process of manufacture the strip A is passed through amachine, which, by means of a die and punch, forms the holes w :r, to receive the barb B, and throws up that part of the strip A between the holes .r 00 and throws down those parts of the strip A which lie outside of the holes or av, respectively, as shown in Fig. 2. To accomplish this the strip Apasses between two opposing dies having conformed faces, to produce the shape described, and at the same. time punch or cut the holes or slits an ac. The strip A lies flat during the whole of L the process of preparation for and fixing the barb. The barb B is fed transversely into the holes ac :vfrom a reel of wire or metal strip,

being cut into the required length coincidently with its insertion into such holes 00 x, the transit of the strip A being momentarily interinitted to permit such insertion. After the barb B is inserted as described the strip A passes, thus furnished with the barb B, between two horizontal metallic rollers, which presses those portions of the strip A between the holes 00 a; and the parts lying outside. of such holes into nearly the same plane, and by reason of part of the strip A being on one side of thebarb B and part of such strip being on the opposite side of such barb, the latter is slightly dented or bent at each holewx, thus preventing any casual removing or withdrawal of the barb B in handling the material orafter the same is placed upon the fence.

What I claim as my invention, anddesire to secure by Letters Patent of the United States, 1s-

The process of manufacturing barbed-fence material which consists in taking a metallic strip, A, about seven-sixteenths of an inch in width,an d of anyv suitable thickness, and pass ing the same flatwise between a stamp and a die having conformed faces, so as to produce the punctures w 00 in and conformation of the strip A shown in Fig. 2, then passing the barb B transversely any desired distance through the punctures a; a: and severing such barb diagonally the desired length, and finally passing such strip A, thus furnished with the barb B, between two horizontal rollers having flat faces, by means whereof the strip A and barb B are pressed into nearly the same plane, thus slightly bending the barb B at the puncturesww aforesaid and firmly seating such barb, substantially as herein described.

In testimony whereof I aifix my signature in presence of two witnesses.
